ROLLER-BAR TIP FOR SPINNING MACHINES.

Application filed August 16, 1921.

To uZl whom it may concern.

Beit known that Lns'rnu B. Run), a citizen of the United States of America, re siding at Gaffney, in the county of Chero lree and State of South Carolina, has in vented new and useful Improvements in Roller-Bar Tips for Spinning Machines, of which the following is a specification.

The object of thefinvention to improve the construction of the roller bar tips for spinning machines to avoid the disadvantages incident to the use of the tips commonly employed, wherein the accumulatiton of lint at the terminals of the bearing or pressure rollers and between the ends of the reduced journals or trunnions of said rollers and the webs of the commercial form of roller bar tips causes a choking or interference with the free movement of the rollers which are usually leather covered, and hence an irregularity in the operation of the spinning machine; and with this object in.

view the invention consists in a construction of which a preferred embodiment is shown in the accompanying drawings, wherein:

Figure l is a view in perspective of a roller bar tip embodying the invention.

Figure 2 is a side view of the same.

Figure 3 is a plan view showing in dotted lines the arrangement of the adjacent ends of the rollers.

The tip as in the ordinary practice is carried by a bar 10 and consists of the inner and outer heads 11 and 12 which are spaced apart to form a guide for the reception of the adjacent trunnions or reduced terminals 13 of the floating or bearing rollers 14 which ordinarily are leather covered and rest upon the roving in traversing the fluted or steel rollers, said heads being connected by a web 15 which in the ordinary practice is extended from the lower to the upper edges of the heads to maintain a separation of the extremities of said roller trunnions or jour-- nals which, however are free to move vertically or longitudinally of the guides formed by the interval or space between said heads.

Inthe ordinary practice the lint winds around the trunnions or tern'iinals oil. the rollers and working into the ends thereof accun'iulates between said ends and the side surfaces of the web and not only interferes with the floating or upward and downward movement of the rollers but jams and chokes them against rotary movement, with Specification of Letters Patent.

Serial No. 492,649.

acent to the lower eds-es oi? the heads, being concaved or cut away at its upper side to leave an open space between the adjacent ends of the trunnions or terminals of the rollers, said web being extended upward at one side to form a narrow rib 16 constituting a shoulder suflicient to prevent the end wise displacement of the rollers, and as a consecpience the lint working into the ends or the trunnions or terminals of the rollers is received in the cut away portion or space 17 between the heads and above the web where it can be supplied with lubricating oil by means of a wick 18 which is fitted in and extends through an opening 19 in the outer head.

With this arrangement of the parts the lint is free to work off of the ends of the trunnions or journal portions of the rollers and even should the same accumulate to a considerable extent in the space provided for the reception thereof it is moistened by the lubricant supplied by the wick and therefore is rendered harmless and incapable oi interfering with the movement either vertically or rotatively of the rollers.

It will be obvious that the ordinary form of roller bar tip wherein the web extends continuously from the lower to the upper edges of the heads may readily be modified to produce the improved tip by cutting away a portion of the web to form the recess 17 while leaving a suifiicient portion of the web to afford stop shoulders 16 to limit the endwise movement of the rollers.

Having described the invention what is claimed as new and useful is 1. A roller bar tip 0 1 spinning machines having spaced heads forming guides for the terminals of the bearing rollers, the space between the heads being open between the ends of the rollers and one of the heads having stop shoulders for limiting the end-- wise moventients of the rollers.

9. A. roller bar tip for spinning machines having spaced heads forming guides for the terminals of the bearing rollers, the heads being connected adjacent to one edge and one of them being provided with a rib fornr ing shoulders to limit the endwise movement of the rollers.

3. A roller bar tip for spinning machines having spaced heads forming guides for the terminals of the bearing rollers, the heads being connected adjacent to their lower edges by a web which is recessed between the extremities of the rollers for the reception of lint clinging to the rollers.

4. A roller bar tip for spinning machines having spaced heads forming guides for the terminals of the bearing rollers the heads being conne'ctedadjacent to the lower edges by a web which is recessed between the extremities of the rollers for the reeeption'oi lint clinging to the rollers, lubricating means being provided to feedthe said recess.

5. A roller bar tip for spinning machines having spaced heads forming guides for the terminals of the bearing rollers the heads being connected adjacent to their lower edges by a web which is recessed between the extremities of the rollers for the reception of lint clinging to the rollers, a lubricating wick being disposed in said recess.

6. A roller bar tip for spinning machines having spaced heads forming guides for the terminals of the bearing rollers. the heads being connected adjacent to their lower edges by a web which is recessed between the extremities of the rollers for the reception of lint clinging to the rollers, one of the heads being provided with an opening in which is fitted a lubricating wick extending into said recess.

In testimony whereof he afiixes his signature.
